5. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically. In addition, the
“TPMS Telltale Warning Light” will turn off and the
graphic in the EVIC will display a new pressure value
instead of dashes (- -), as long no tire pressure is below
the low pressure warning limit in any of the four active
road tires.
NOTE:The vehicle may need to be driven for up to
20 minutes above 15 mph (25 km/h) in order for the
TPMS to receive this information.

FUEL REQUIREMENTS
3.3L/3.8L Gasoline Engine
These engines are designed to meet all
emissions regulations and provide excel-
lent fuel economy and performance when
using high-quality unleaded “regular”
gasoline having an octane rating of 87. The
use of premium gasoline is not recom-
mended, as it will not provide any benefit over regular
gasoline in these engines.
384 STARTING AND OPERATING

4.0L Gasoline Engine
This engine is designed to meet all emis-
sions regulations and provide satisfactory
fuel economy and performance when us-
ing high-quality unleaded gasoline having
an octane range of 87 to 89. The manufac-
turer recommends the use of 89 octane for
optimum performance. The use of premium gasoline is
not recommended, as it will not provide any benefit over
regular gasoline in these engines.
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required.
Poor quality gasoline can cause problems such as hard
starting, stalling and hesitations. If you experience these
symptoms, try another brand of “regular” gasoline be-
fore considering service for the vehicle. Over 40 automobile manufacturers around the world
have issued and endorsed consistent gasoline specifica-
tions (the World Wide Fuel Charter, WWFC) to define
fuel properties necessary to deliver enhanced emissions,
engine performance, and durability for your vehicle. The
manufacturer recommends the use of gasolines that meet
the WWFC specifications if they are available.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gasoline”.
Reformulated gasolines contain oxygenates, and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.
The manufacturer supports the use of reformulated gaso-
lines. Properly blended reformulated gasolines will pro-
vide excellent performance and durability of engine and
fuel system components.5
STARTING AND OPERATING 385

Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as 10% ethanol, MTBE, and ETBE. Oxygen-
ates are required in some areas of the country during the
winter months to reduce carbon monoxide emissions.
Fuels blended with these oxygenates may be used in
your vehicle.
CAUTION!
DO NOT use gasolines containing Methanol or E85
Ethanol. Use of these blends may result in starting
and driveability problems and may damage critical
fuel system components.
Problems that result from using methanol/gasoline or
E85 Ethanol blends are not the responsibility of the
manufacturer. While MTBE is an oxygenate made from
Methanol, it does not have the negative effects of
Methanol.
E-85 Usage In Non-Flex Fuel Vehicles
Non-FFV vehicles are compatible with gasoline contain-
ing 10% ethanol (E10). Gasoline with higher ethanol
content may void the vehicle’s warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms:
•operate in a lean mode
•OBD II “Malfunction Indicator Light” on
•poor engine performance
•poor cold start and cold drivability
•increased risk for fuel system component corrosion
To fix a Non-FFV vehicle inadvertently fueled once with
E-85 perform the following:
•drain the fuel tank (see your authorized dealer)
•change the engine oil and oil filter
386 STARTING AND OPERATING

•disconnect and reconnect the battery to reset the
engine controller memory
More extensive repairs will be required for prolonged
exposure to E-85 fuel.
MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emission system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content
of gasoline may not be indicated on the gasoline pump,
therefore, you should ask your gasoline retailer whether
the gasoline contains MMT. It is even more important to look for gasolines without
MMT in Canada, because MMT can be used at levels
higher than those allowed in the United States.
MMT is prohibited in Federal and California reformu-
lated gasolines.Materials Added to Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives are not needed under
normal conditions and would result in additional cost.
Therefore you should not have to add anything to the
fuel.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
5
STARTING AND OPERATING 387

•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance
and damage the emission control system.
•An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your authorized dealer for service assistance.
•The use of fuel additives which are now being sold as
octane enhancers is not recommended. Most of these
products contain high concentrations of methanol.
Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives is not
the responsibility of the manufacturer.
NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
•To prevent carbon monoxide poisoning DO NOT
inhale exhaust gases. They contain carbon monox-
ide, a colorless and odorless gas which can kill.
•NEVER run the engine in a closed area, such as a
garage, and NEVER sit in a parked vehicle with
the engine running for an extended period. If the
vehicle is stopped in an open area with the engine
running for more than a short period, adjust the
ventilation system to force fresh, outside air into
the vehicle.
(Continued)
388 STARTING AND OPERATING

WARNING! (Continued)
•Guard against carbon monoxide with proper
maintenance. Have the exhaust system inspected
every time the vehicle is raised. Have any abnor-
mal conditions repaired promptly. Until repaired,
drive with all side windows fully open.
•Keep the liftgate closed when driving your vehicle
to prevent carbon monoxide and other poisonous
exhaust gases from entering the vehicle.
FLEXIBLE FUEL (3.3L ENGINES ONLY) — IF
EQUIPPED
E-85 General Information
The information in this section is for Flexible Fuel Ve-
hicles (FFV) only. These vehicles can be identified by the
unique fuel filler door label that statesEthanol (E-85) or
Unleaded Gasoline Only. This section only covers those
subjects that are unique to these vehicles. Please refer to the other sections of this manual for information on
features that are common between Flexible Fuel and
gasoline only powered vehicles.E-85 Fuel Cap

STARTING AND OPERATING 389

For best results, a refueling pattern that avoids alternat-
ing between E-85 and unleaded gasoline is recom-
mended.
When you do switch fuel types, it is recommended that:
•you do not add less than 5 gal (19 L) when refueling
•you drive the vehicle immediately after refueling for at
least 5 miles (8 km)
Observing these precautions will avoid possible hard
starting and/or significant deterioration in driveability
during warm up.
NOTE:
•Use seasonally adjusted E-85 fuel (ASTM D5798). With
non-seasonally adjusted E-85 fuel, you may experience
hard starting and rough idle following start-up, even if
the above recommendations are followed, especially
when the ambient temperature is below 32°F (0°C).
•Some additives used in regular gasoline are not fully
compatible with E–85 and may form deposits in your
engine. To eliminate driveability issues that may be
caused by these deposits, a supplemental gasoline
additive, such as MOPAR Injector Cleanup or
Techron may be used.
Selection Of Engine Oil For Flexible Fuel Vehicles
E-85 and Gasoline Vehicles
FFV vehicles operated on E–85 require specially formu-
lated engine oils. These special requirements are included
in MOPAR engine oils, and in equivalent oils meeting
Chrysler Specification MS-6395. The manufacturer only
recommends engine oils that are API Certified and meet
the requirements of Material Standard MS-6395. MS-6395
contains additional requirements, developed during ex-
tensive fleet testing, to provide additional protection to
Chrysler LLC engines. Use MOPAR or an equivalent oil
meeting the specification MS-6395.5
STARTING AND OPERATING 391

Starting
The characteristics of E-85 fuel make it unsuitable for use
when ambient temperatures fall below 0°F (-18°C). In the
range of 0°F (-18°C) to 32°F (0°C), you may experience an
increase in the time it takes for your engine to start, and
a deterioration in driveability (sags and/or hesitations)
until the engine is fully warmed up.
NOTE:Use of the engine block heater (if equipped) is
beneficial for E-85 startability when the ambient tempera-
ture is less than 32°F (0°C).
Cruising Range
Because E-85 fuel contains less energy per gallon/liter
than gasoline, you will experience an increase in fuel
consumption. You can expect your miles per gallon
(mpg)/miles per liter and your driving range to decrease
by about 30% compared to gasoline operation.
Replacement Parts
Many components in your Flexible Fuel Vehicle (FFV) are
designed to be compatible with ethanol. Always be sure
that your vehicle is serviced with correct ethanol com-
patible parts.
CAUTION!
Replacing fuel system components with non-ethanol
compatible components can damage your vehicle.
Maintenance
If you operate the vehicle using E-85 fuel, follow the
maintenance schedule section of this manual.
CAUTION!
Do not use ethanol mixture greater than 85% in your
vehicle. It will cause difficulty in cold starting and
may affect driveability.
